Former astronaut Buzz Aldrin has been keeping tabs on the Kardashians during his hospital stay in Christchurch, New Zealand. The 86-year-old tweeted a photo of himself reading a tabloid featuring “Keeping up with the Kardashians” reality star Kim Kardashian on Sunday.

Aldrin, one of the first people to walk on the moon, was medically evacuated from the South Pole, according to the National Science Foundation.

Last week, he was visiting Antarctica as a tourist when he fell ill. He was flown to Christchurch from McMurdo Station, a U.S. research center on the Antarctic coast.Tour company White Desert said Aldrin has fluid in his lungs, but was responding well to antibiotics.
